If I wouldn't have been in such a time crunch I could have drilled and tapped the holds for the Motor mounts. The tabs are there for them they were just not machined. So it could be done pretty easily. All in all it was still a cheaper conversion. I can find a lot of Sonota engines with less than 100K on them for less than $500.00. I only paid $350 for this one which included my core charge, bcs I wanted to keep my original engine. It was also closer to where I live. The others would have been a 200 mile round trip and a day off of work to get them. It had a little over 100K on it.
